Application tiled April 15, 1911. Serial No. 621,263.

"Be it. known that I, Groncn Koi-mic, a subject of ,the Kingr of Saxony, residing at Gautzsch, near Leipzig, in Germany, have invented a certain new and useful improvement in Adding-Machines, of which the following is a specification.

'Une-object of the present invent-ion is to provide certain improvements in the mechanism of adding,r machines.

Another object is to provide, in combination with the improved adding,T mechanism, improved mechanism for setting up the totals iii-type, and printing same, together Withnieanf; whereby said tyyni-sctt ing` mechanism can be actuated from the keyl'ioard, independently of the adding;V mcehanisn'i.

The invention illustrated in the accompartying drawing, in which, l

-Figure l is a sideelcvation of the machine With parts broken away, and Fig. 2 a plan view. Fig. 3 is a. vertical section of the iront part of the machine, drawn to a larger scale and partly broken away. Fig. 4 is a ver- 1 tical section of the rear part of the machine, drawn tothe same scale as Fig. 3. Fig. 5

^ is a plan View oii' the mechanism shown in Fig. 3, partly in section and with parts 'broken away. Fig. 6 is a plan View of the mechanism shown in Fig. 4, partlyin section and with parts broken away. Fig. 7 is a side elevation of part of the mechanism for adjusting the types from the keyboard, and F ig; 8 is a plan View thereof, Figs. 9 and 10 'being elevations ot' part of this mechanism, viewed from the lett. hand side of F igs? and 8, and showing two diiferent positions. Figs. 11 and 11 are respectively a side elevation and a plan of a detail of the mechanism shown in Figs. 7 to 10.

Fig. 12 is aside elevation of part of the addg ing mechanism. Fig. 13 shows part of the adding mechanism viewed from the front of the machine, Fi, z.f14 being a side 'view thereof, and Fig. 15 a plan view. Figs. 16 to 18 show the devices for actuating the adding mechanism from the keyboard, and Figs. 19 to Qlwshow details or. these devices.

The front ,I part of the machine is horizontally divided by two platforms formed by transverse bars 1, 2 (Fig. 3), each of which has ten equidistant holes forming guides for the shanks 3 of keys 4 supported by springs There are nine transverse banks of keys, but in the drawing two of hase banks are omitted. Each bank comprises ten keys, and the keys in each vertical row bear the numerals l to 9, counting from front to rear. The iirst row represents the units, the second row the tens, the third row hundreds and lso forth. The length of the key Shanks are so proportioned that the keys 4 rise in steps toward the rear, enabling the nun'lerals to be conveniently surveyed and the machine to be operated with eas'e. Each key shank 3 carries a small roller', engaging a groove in a rotatable, vert-ical cam cylinder 6, so that said cylinder is caused to make a complete revolution during thev rdepression and ascent of the key. Each cam 'cylinder is connected by a ten toothed bevel wheel 7 with a bevel Wheel 8 which has the same number of teeth and is loosely mounted on a pin 9 projecting laterally from one of the transverse bars 1, so that said bevel Wheel 8 is rotated by the rotation of the cylinder 6. This arrangement is best shown in Figs. 16-to 18.' Each bevel Wheel 8 is ixed to a toothed disk or mutilated gear Wheel 10 having a number of teeth corresponding with the numeral on the key for operating the respective cam cylinder.

Close to each vertical row of keys there is rotatably mounted.` above t-he bars 1, a shaft 12 to which are fixed nine toothed Wheels 13; each of the latter has ten teeth and meshes with the teeth on one ofl the disks 10, so that. the latter Wheels 13 and rotate the shaft 12 through angles proportionate to the number of teeth on the, disks 10. Keyed to the rear end of each shaft 12 there is a bevel Wheel 14 (Fig. 3) which meshes with a bevel Wheel 16 loosely mounted on a shaft 15; to thebevel Wheel 16 is fixed a toothed Wheel 17 which can be. geared by two similar toothcdwheels 18, 19 with a toothed wheel 22 carried by a lever 21 pivoted on a spindle 20. (Fig. 12.) To each toothed wheel 22 there is fixed a disk 23, on the circumference of Which are marked equidistant numerals 0 to 9. The disks 23 are normally held in position to exhibit the zero signs by springs 25 engaging Apins 24 projecting,r from cams 26 fixed to said disks the numerals on the latter are visible through apertures provided in the cover plate.- Depression of a key 4 causes the respective cylinder 6 to rotate; the latter drives by means of thebevel Wheels 7 8 and disk 10 the shaft 12 belonging to the correspendingr row7 the rotation of said shaft then being transmitted by the bevel Wheels 14, 16

can severally drive the and wheels 17, 18, 19 to the toothed Wheel 26 and to the disk 23 thereon7 so that this disk is rotated through an angle which causes a numeral corresponding to that on the key to appear in place of thepreviously exhibited naught. rillius the operator is able to see if he has operated the ke bearing the numeral which he had in min spring 25 attached to the pin 24. The zei-0- izing of the disks 23 is eti'ected by means of a spring supported key 29 (Fig. 1) to which the levers 21 are collectively connected by a bellcrank lever 28. i By depressing said key 29 the levers 21 are rocked and caused to lift the wheels. 22 out of mesh with the Wheels 19, whereupon the stretched spring 25 pulls the rotated disk 23 back to zero position. Release of the key 29 allows the levers 21 to return to normal position. If the spring 25 of the rotated disk is in a dead-point position, disabling it. trom rotating the disk when the wheel 22 is lifted out of mesh, the cam 2G strikes an abutment formed by a curved tooth of a kind of comb 27, and ro-l tation of the disk is-thus initiated, enabling the spring to perform its function. Parallel with each shaft 12 there is an'- other rotatableshaft 30 to which are tiredv hooked levers 32 opposite cam disks 31 fixed to the toothed disks 1o, Figs. is, 17, is. The hooks are held against the, cams 31 by means of a torsion spring on the shaft 80. The. crests of the cam disks 31 (Figs. 21,

21a) severally correspond in length with the.

' takes place the cam 31 causes the lever 32 to be raised. This movement rotates the shaft 30 through a certain angle and causes a pawl 33 at the rear end of said shaft to .be disengaged from a ratchet Wheel34 on the adjacent shaft 12, enabling` the .latter to be rotated by the toothed disk 10 and wheel 13. As soon as the toothed part of the-disk 10 has cleared the wheel 13, the point of the hooked lever 32 passes onto'the lower path of. the cam 31 andthe shaft 30. is rotated back, causing the pawl 33 to rengage the ratchet. wheel 34 on the shaft 12. This insures precision by preventing movement. of

the .shaft 12 except when operated by a key. For additionalsecurity there is arranged at. the trout. end of cach shaft 12 a small ratchet wheel 35 with a pawl 36 which latter prevents the shaft 12 from rotating backward.

Behind thc disks 23 there is a row oi3 addingl disks 37. (Figs. 13, 14, 15) which are likewise marked with the numerals 9-0, The disks 37 are carried by double-armed levers 39 mounted on a shaft 3S. The levers 39 abut. with their tree hooked ends against a rod 41` which extends' through the Width The rot-a- -tion of the disk 23 and cam 26 stretches the of the machine'and is mounted in slots 40. in the frame of the machine. The disks 37 are cup-shaped and are loosely mounted on the shaft. 42 carried by the levers 39; eachl of these disks is provided inside with a. pawl which engages a small ratchet Wheel-1ntegral with a pinion 43 meshing with onefof the above-mentioned wheels 19.

To the shaft 42 there are fixed, for each disk 37 a" disk 44, providedwith a tooth,.and a cam 45` connected to a spring'46n'hich i'iorriiiilly` holds the disk 37 in its zero posit-ion. Above the rod 41 there is a fixed s the gears being so proportioned that at each aft 47 carrying loosely mounted equidistant pairs of levers '48, 48, the lower ends of each pair forming.-

revolutionof one adding disk the nexton`l.. is moved one unit.. By this means the y' of an adding operation is exhibited, andthesum may be transferred to paper. In orden to enable the figures to be seen, inspectirm` the cover,'ove1"4 apertures are provided in the adding` disks.,

The adding disks 37 can be thrown out gear by means of a key 55, (Fig. 1) 'con'- neeted by a fork-shaped bell crank lever v54 to the rod 41. The cams 45 on the-disks;

37, coacting with the comb 27, pcrform: function similar to that of the cams 26,

when the springs 46 are at a dead center.4 The levers 48 carrying the transfer wheels". 50, 51. have upwardly projecting fingerl shaped ends, abutting against hand-leversv 53 mounted on a spindle 52; the said levers ion 53 project through slots in the cover plate of the machine. These levers 53 enable the transfer wheels to be disengaged atany sec- 'computed separately. The levers 53 ca be also used forv subtraction and for rectifying mistakes due to operating wrong keys. Foi

adding the amounts. of hills; checks or the like. as mar c counting o.",ks as is necessary art-y thrown out of gear. Fonthis purpose the countmg disks may be so mounted that each ot them may be separately lifted out ofl engagement with the gear wheels. Likewise. the disengaging rod 41 behind the .second register may he divided so that by ot gear; the other part remaining in action. The cover pa its over the counting wheels, provided willi inspection apertures, may be f pushing hack one part of it, the counting uuchanism belonging thereto is thrown out.`

'actuated levers 56.

so arranged that they also take part in the slight movement when the counting mechanism is thrown out of gear.

Underneatli eachvertical row. of key Shanks .8 there is a lever 56 pivoted at 57 with a spring 58 tending to elevate its front end. Adjacent t9 each lever 56 are pillars 59 which are staggered so that they stand alternately at opposite sides of the lever (Figs. 7 and 8). On these pillars are mount-l ed movable arms 60 (Figs. 11, 11a). Each of the latter has a finger 61 which, engages a bell crank 62, the l.latter being pivoted to 4the pillar and having an arm projecting under the lever 56. At the centralA part of arm 60 there is a slot 63 into which projects a pin 64 fixed to the lower end of the adjacent key shank 3, and the arm hasat its free end a lateral pin 65 which projects over the lever 56. Hence, if the key is depressed it rotates the arm 60 and the lever 56 is depressed by the pin 65, and the nger 61 actuates -the bell crank 62 until the latter strikes the lever 56, and limits its downward movement.

The levers 56 are bent inward behind their pivots 57 in such a manner that the rear ends of the same lie comparatively close together (Fig. 6). At the rear end ot'y each lever 56 there is a lateral pin 66 (Fig. 4) which projects into` a slot 67 in a bell crank lever 68. The levers 68 are'fulcrumed on a shaft 69 extending through the Width of the machine and'I connected byV links 70 to levers 72-pivoted at 71. levers 72 extends through a casing 73 containing ten parallel plates 74, stepped at top and bottom, capable of vertical movement in said casing. These plates 74 rest with their bases on the floor of the casing 73, and are provided with curved slots 75 for engagement with pins 76 projecting laterally from the levers 72. Resting loosely.V on the upper edge of each plate 74 are ten spring pressed types 77 capable of horizontal movement, representing in series from top to bottom the numerals 0 to 9. These types can be lifted out of the easing 73 into printing position, by raising the plates 74."The plates 74 are raised by means of the levers 72 actuated by the key- The extent of the litting movement depends on the position of the actua-led key relatively to the pivot 57, the parts -being so proportioned that each key is adapted to'lift into printing position the type representing the value of the key. The plates 74 are racked and engaged by pawls 83. which hold them in lifted position.

.Each lever 72 carries at its free end a spring pressedslide 78, which, when the lever is in normal position, serves as abutment for one of a series of ten hammers 80 pivoted at 79. These hammers are`adapted to actuate spring nressed pins 82 horizon- Each of the tallymiovable in guides 81, these pins being arranged opposite the vertical series of types, in position to thrust the types in printing position toward the paper on the intermittently rotating platen 84.

The hammers 80 are actuated by means o f a rod 86 carried by arms 85 which are pivoted to the trame oi the machine, said rod being connected to springs 87. vThe Varm on the right hand side is provided with a finger 88 (Fig. 1) which bears against one arm of a bell crank 91, the movement of which is limited by a stop 9 0. A. pin 92, on the other arm of this bell crank projects into the mouth 98 of a pawl 95, pivoted yto a double armed lever 94. By depressing the front.v end of the lever 94 the pand-95 is lifted and caused to rotate the bell crank91' y thus enabling the springs 87 to rock the arms 85 and swing the rod 86 against the ham- 85 mers 80. Atthe same time a link 96 'pivoted to the rear part of the lever 94 rocks a frame 98 pivoted at 97. This frame 98 swin'g`s,.\` rearward to serve as an abutment :forv the hammer levers when the latter. fly ,back from`the spring pressed pins 82. f 4Mounted at the lower part of the' rightv hand arm 85 there isa roller' 99, which,V when 'the arm 85 swings vforward is placed' over the curved rear end ofV the lever 94,` so that duringthe upward movement of said curved part the latter strikes the roller and,v restores the arm 85 to itsI original position. in Whiph the said arm is rengaged 'with' the bell crank 91. Consequently thema# chine can be, operated again immediately after the type has been printed.

The lever 94 is connected by a slotted link l ,y 100 with the bell crank lever 28 acting oii i the levers 21, so that every time the lever'IO 94'is depressed the disks 23, are released', enabling the zeroizing devices to act. the right hand side of the casing 73"thereis a horizontally movable slide 101l (Fig. 6), the forward end of'which is held b a sprin in the path of the rod 86 and whic is struc when the rod 86 moves back. The slide 101 engages, by means of its rear end andV a lateral pin 102, the free ends of two vertically depending levers 103 and 104. The lever 103 1s pivoted at 105 and carries at its. upper end an anchor shaped double pa'wlV 106 which at every movement imparted to it rotates the ratchet Wheel 108, actin 'on the ribbon 'gear 107 g if resistance is o ered by the gear, as is the case when the ribbon has been wound off one reel, the said double` pawl automatically reverses van(ii\works in .the opposite direction, so that "thbribbon is wound oit the full reel ontojthe empty one. v M

The lever 104 is pivoted at 109 and acts with its upper end on the paper feed mechanism 110; its lower end carrie rotatory "f labutment plate 111 provided with three 130 ahollow cap, and moved along the longi-v tudinal slots in the cap 124; and bar 125. This knife may be operated by hand or mechanical means.

Mounted at the front of the machine in front of the first bank of keys there is a transverse bar 112 3 and o) extending through the width of the machine, which abuts against the ends of the shafts 12 and is connected by slidable rods 113 to a bar 114 provided with projections like the teeth' of a rake, which project toward. the toothed wheels 13 in front of them, on the shafts 12 in position for engaging the same it each end of the bar 112 there is soup-shaped projection 115 engaged with a cam 11i' fixed to a rotatable shaft 11G so that by rotation of the shaft 1 16 the bars 112, 114 can be shifted forward and rearward. The .shaft 11G 'is rotated by a link 120, connecting an arm 118 on the shaft to a handle 119; this link can 'be locked in its end positions'by means of notches engaging fixed tooth. When the bars 112, 1111 are moved forward the bar 114 moves all., the shafts 12 with it. so that the bevel. wheels at the rear ends of said shaft are disengaged from thefbevcl wheels 16; consequently when the keys are depressed the counting wheels remain stationary but the numerals ongthe keys printed on the paper. The bevel wheels lliure brought into-mesh again with the bevel wheels 1G by moving the bars 112, 114Y rearward, and by operating the keys and the lever 911, both series of counting wheels and the. printing device are caused to work together, the first series of counting wheels being, however, -zeroized by each depression of the. lever 94..y

At the front of the machine on the base of the same, there is mounted on. Apillar 121 a lever 122 having its front end bent transversely across the levers 56, the lever 122 being normally held up by a spring 123. By depressing the lever 122 all the levers 56 are depressed sufficiently to prevent the actuation thereof by thelevers 60, so that the printing mechanism is put'out of action,

the counting mechanism remaining, how-l ever, ingear..
